Continuity mistake: When Joe is first in the cat and him and 22 see each other, the cat has a harness on. In the next shot when they leave the room, the harness is gone. (00:38:20)
Continuity mistake: Isaac is wearing tan or khaki pants but the video of him getting "beamed up" to the spaceship shows dark blue pants. (00:18:15)
Continuity mistake: The amount and location of dirt on Christine's face is inconsistent, ranging from being very thick and obvious to barely visible, if at all. Sometimes it extends down her neck on the right side. When her hair covers most of her face, no dirt is visible - until she turns her head and the hair is away from her face. The intensity and location of the redness on her neck also varies. (00:03:31 - 00:04:48)
Continuity mistake: Mara is wearing a white long sleeve jersey when in the Dalton twins' car accident and when Dylan finds her in the water washing off blood. Dylan offers her the gray sweat suit he has in his backpack, but Mara says she isn't wearing it (because they wore those clothes at the police station). When Mara stands up, she has on a dark green T-shirt with a lighter green large circular design on the front. Mara is wearing the green top when she gets to quarantine, as well as later in the movie. This is obviously Mara's top, so where did it come from after she refused to wear the gray sweat suit from Dylan's backpack? (00:33:42 - 00:35:02)
Suggested correction: After rewatching the movie, I noticed that Dylan was POSSIBLY wearing this T-shirt under his jean jacket on his first day of school; the shirts look similar, but little can be seen because it is under the jean jacket. At the same time, Dylan's backpack at the accident scene did not look full enough to contain both parts of the sweatsuit, so it is a stretch to believe the T-shirt was also inside. Moreover, Dylan told Mara that he had a crush on her for two years, so the "old" T-shirt would have just happened to be in this backpack under the sweatsuit worn at the police station. Dylan is thinner than Mara, so it is unlikely that his T-shirt would fit her. When I rewatched the movie, I noticed that the T-shirt in question looked navy blue when Dylan had it on but green when Mara was wearing it.
Continuity mistake: Mikey and his friend are smoking the same inch-long joint by the back door which gets passed back and forth - no way they could keep holding/smoking it for that long given how short it was to start with. (00:04:50)
Plot hole: After the incident in Chemistry class, Adam was taken to the hospital where he was diagnosed with schizophrenia. Next, Adam found out that he was expelled from school. What happened during Chemistry class was attributed to Adam's "first psychotic break" - which would fall under a medical condition for which Adam could not have prevented or controlled. The Department Of Education has laws protecting students like Adam (Individuals with Disabilities Education Act or IDEA, enacted in 1975), and the school is required to meet the child's / student's needs. An Individual Education Program (IEP) should have been prepared for Adam by his school, so the expulsion served to further the plot. (00:06:00 - 00:06:30)
Continuity mistake: Whilst Jung-seok is driving with his family on the first day of the zombie outbreak, after he says "All other roads must be blocked", his sister looks to the left to face her son in the back seat. The shot then cuts to focus on Jung-seok, and the sister can now be seen looking straight forwards out the window. (00:01:45)
Visible crew/equipment: Sara is at the front door video intercom. As the man from the Department of Sanitation is leaving, you can see crew/equipment visible in the reflection. (00:27:15)
Continuity mistake: The kids are in the car with their dad, and despite the best efforts from the youngest, they are reached by his teacher. As the dad starts the "You were killing us" joke, his hand is on/off the steering wheel between shots more than once. (00:07:15)
Character mistake: NYPD officers have their guns drawn toward the elevator in the Carrington Hotel. When the door opens, Borz, wearing an unbuttoned Carrington jacket - but not the hat or white gloves that the doormen wear - is told by an officer to "hold it" and states that he's "just a doorman." The officer backs up and allows Borz to leave. A police officer would not simply accept the word of anyone in this situation. The person would be handcuffed and detained until the situation is under control and the police determine he was not (or was) involved. (01:24:41 - 01:35:02)
Factual error: TV reporters said "home invasions" and mentioned trying to find the people who were responsible for the "70 robberies." Lance (in prison), was talking to a woman who was going to write a book and told her he got "twelve years" for "fifteen counts of robbery and vandalism." The crime Lance and the rest of the group were committing fits the legal definition of "burglary" in Illinois (basically, entering an occupied structure with the intent to commit a felony or theft inside; the structure does not have to be occupied at the time of the act). Because there happened to be someone at home during their last (intended) "burglary", this offense would be classified as a "robbery."
Continuity mistake: The sizes, locations, and smoothness of the pieces of glass remaining in the wall mirror after Aidan smashes it with a bat change. Initially, there were a few large and several smaller jagged-edged pieces around the top and upper-half of the right side. Later, there were four relatively large smooth-edged pieces spaced around the upper half of the mirror - one in each upper corner and one on each side at the middle. (00:15:48 - 00:19:33)
Other mistake: The scraping sound is not coming from the man "scraping" his windshield. The snow is easily brushed off and there is no icy coating below the "fluffy" snow to realistically produce the sound of scraping ice off a windshield. (00:00:35)
Continuity mistake: In the opening scene, pay attention to Evan's girlfriend's glass. When Isaac gets up and goes inside, the amount of liquid in her glass slightly changes between shots.
Other mistake: In this film, when they find the picture of Nancy (from the original Craft film), the image is of Nancy in the restroom of the original movie. If you watch the original film, the image that was used of Nancy shown in the new film would have taken place during the scene where Nancy, Bonnie, and Rochelle confront Sarah about wanting out of the coven. But during that scene, no cameras were in sight and nobody was taking pictures.
Factual error: The pilot is flying from the left-hand seat. Helos are flown from the right side. (01:23:00 - 01:25:00)
Continuity mistake: There are some continuity problems during the cafeteria scene where Fern is being introduced to her co-workers. Fern is holding a banana, peeled almost to the bottom, and has several slices of banana on her peanut butter sandwich. There is another banana peel on her paper lunch bag. Fern is shown taking a bite of her sandwich. A little later, Fern is holding a partially peeled banana but no slices can be seen on her sandwich. If this is her second sandwich, she already peeled two bananas. (00:05:59 - 00:06:32)
Continuity mistake: When Johanna and the Captain are being chased by Mr Almay and his associates, their position in the wagon changes. First Johanna is on the Captain's left. Next shot she is on his right. Next shot she is back on his left. (00:42:14)
Continuity mistake: Views of Michelle's car wreck were inconsistent. When the car veered to the right and was headed toward the tree, the driver's view showed most of the car was to the left of the tree trunk. On impact, it looked like the right side headlight hit the middle of the tree trunk. Michelle got out and a rear view showed the tree trunk roughly lined up with the steering wheel (i.e, more than half of the car was to the right of the trunk). After impact, both headlights were shining in front of the tree.
Continuity mistake: In the opening scene, the blue car is parked on the far right of the screen or at least one car length from the doctor's front door. Dr. Huggins says goodbye to the couple with the baby, who walk toward their car. After the burglars-to-be (turned robbers) are shown watching from a distance, the camera returns to the doctor's front door. The blue car is now near the center of the screen and it drives away toward the right of the screen - going past the place it had been parked.
